Description

Markers tested: Cortisol (morning, noon, evening, and night)

What is cortisol?

Cortisol is one of the stress hormones produced in adrenal glands. It has important role in metabolism to break down carbohydrates, lipids, and proteins. A well defined 24 hour circadian pattern is an important characteristic of cortisol. The levels peaks around 8 am and then gradually drops throughout the day.

Why measure cortisol levels?

Change in the normal cortisol circadian rhythm can be caused by many issues including chronic stress, adrenal fatigue, burnout, or problems with adrenal glands. Chronically high levels are especially bad as they may result in increased appetite and weight gain. Excessive levels cause muscle loss, immune suppression, water retention, and bloating. Low levels are also bad since deficiency can result in fatigue, sluggishness, and low energy.

How to test for cortisol levels?

An easy, low cost method of measuring your levels is by using an cortisol level test at home. Simply order this 4 point salivary cortisol test kit, collect the sample at home, ship it for free to our world class CLIA-certified labs, and find out your levels within days. Unlike a cortisol blood test a saliva sample makes it especially useful for those fearful of needles.

We also offer a cortisol am test and cortisol pm test as an alternative. The Cortisol AM-PM Saliva Test Kit measures levels in the morning and evening.

Learn more (1): What are Adrenal Glands?

The adrenal glands are a pair of glands on top of each kidney. They produce five key hormones:

Catabolic hormones: they act as a balance to anabolic hormones by accumulating fat and helping raise blood sugar by breaking down muscles and bones; cortisol is a good example

Learn more (2): Cortisol and Pregnancy:

The circadian rhythm of free cortisol in pregnant women starts to change around 20th week of pregnancy. Although the diurnal rhythm remains, mean levels increase 1.5-2-times and morning levels increase several times higher than normal levels. Another important observation is that the peak levels lag behind approximately 90 minutes likely due to delayed activation of the HPA axis. The external stimulation of CRH does not increase ACTH as well as salivary cortisol levels support this observation. The levels return back to normal after 5-7 days of delivery.

It will mark your cortisol levels on a healthy range for the time of the day and will specify what are the expected low and high ranges. It will briefly discuss what your numbers mean and next steps you should take to maintain healthy levels.

Q: Can I use my insurance to pay for the test?

A: You can use HSA (or FSA/MSA/HRA) accounts to pay for the tests since these are prescription tests (for further confirmation, please check the IRS publication#969). However, please ensure you are not going outside your specified max and min deductible limits. We do not have the capability to process the insurance claim. Since insurance plans vary for individuals we can not guarantee your HSA payment will always be processed by your plan. We suggest talking to your insurance provider if you have any questions.

Q: How reliable are my tests and how do I ensure my results are accurate?

A: Measuring cortisol levels using saliva is a well researched and thoroughly documented procedure. If fact, it is reliably accurate and one of the best way to testing cortisol levels.

The variations in results are mainly from two sources: the way samples are collected and the variation from lab-to-lab. Levels are highest in the morning, when we are most energetic, and then drop during the day.

To minimize this variation, you should collect the sample within 30-60 minutes of waking up, without eating, brushing or putting anything else in your mouth that might contaminate the sample.

To minimize the variation from labs, we have partnered with CLIA-certified labs that are regulated by the states, as well as Centers for Medicare and Medicaid Services (CMS). Majority of the tests from these labs are FDA approved to ensure they meet the proper regulatory requirements. Additionally, the College of American Pathologists (CAP) requires inter-laboratory tests to ensure the ranges established by each lab do not drift or are not out of acceptable ranges. This is done by regularly testing reference samples between different labs. Finally, the labs test thousands of samples for different age groups and health conditions, and have well established reference data to compare your results against this large pool.

Q: Can you recommend what therapy should I take for cortisol levels high or low?

A: Unfortunately, no. As a lab test provider we can only test and report out data from your sample. We are not authorized to provide any medical recommendations. But we strongly encourage you to discuss the results with your doctor for next steps.

Reasons to Check

5 reasons for testing cortisol levels:

It is the first step to understand why you start to feel tired in the afternoon and evening. Our at home cortisol test kit can help understand your energy levels throughout the day.

Long term mental or emotional stress can raise the stress hormone levels which manifest into weight gain and adrenal fatigue. Stress, anxiety, and depression are commonly observed when levels are high. Cortisol lab test is an easy first step in understanding how your body is handling stress and what life style changes might be required to maintain health.

If you are struggling to loose weight, a strong possibility of cortisol levels high should be assessed. It is also the first step to assess whether a test for low or high ACTH levels might be required. A cortisol saliva test kit is a great way to check adrenal fatigue.
